Answer:

[tex]sin\Theta[/tex] will be equal to 0.9035

Step-by-step explanation:

We have given [tex]cos\Theta =\frac{3}{7}=0.4285[/tex]

So [tex]\Theta =cos^{-1}(0.4285)=64.623^{\circ}[/tex]

Now we have to find the value of [tex]sin\Theta[/tex]

So [tex]sin(64.623)=0.9035[/tex]

So value of [tex]sin\Theta[/tex] will be 0.9035

We can also find the value of [tex]sin\Theta[/tex] by Pythagoras theorem
